Embodiment
To make the purpose of this utility model, technical solution and advantage clearer, implement below in conjunction with the utility model
Attached drawing in example, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that described reality
It is only the utility model part of the embodiment to apply example, instead of all the embodiments.Based on the embodiment in the utility model,
Those of ordinary skill in the art's all other embodiments obtained without making creative work, belong to this reality
With novel protected scope.
Fig. 1 is the structure diagram for the compound nonwoven cloth that the utility model embodiment provides.
As shown in Figure 1, the utility model embodiment provides a kind of compound nonwoven cloth, which includes setting gradually
The first nonwoven layer 1, pulp layer 2, the second nonwoven layer 3 and the 3rd nonwoven layer 4.Paper pulp has that cost is low, moisture-absorbing moisture-keeping
The characteristics of effect is good, but tensile strength is poor at the same time；Common single-layer nonwoven has the advantages that the flexibility of similar paper, but at the same time
Have the shortcomings that endurance strength is poor, it is easily rupturable to be pullled, it is not wear-resisting, do not absorb water.And the technical program passes through by pulp layer and separately
Outer three layers of nonwoven layer is compound, obtains a kind of compound nonwoven cloth, has soft, relatively strong thick and solid degree, good water absorption concurrently, pulling force is strong in length and breadth
The features such as degree is balanced, jacquard weave three-dimensional sense is strong.
Preferably, the first nonwoven layer 1 and the 3rd nonwoven layer 4 are wet nonwoven fabrics, the second woven fabric layer 3 for dry method without
Woven fabric.In addition, according to actual conditions, the first nonwoven layer 1 and the 3rd nonwoven layer 4 can also be dry method non-woven fabrics, second
Woven fabric layer 3 is wet nonwoven fabrics.
Preferably, the first nonwoven layer 1 and the 3rd nonwoven layer 4 are spunlace non-woven cloth, spunlace non-woven cloth master here
It is polyester fiber and viscose fiber to want component, and viscose fiber is natural regeneration cellulose fibre, therefore more environmentally friendly.It is in addition, viscous
Glue surface material also has the advantages that softness, good water absorption, overhangs that property is good, skin sense is good, but there is also easily shrink, repeatedly after moisture absorption at the same time
After washing feel harden, easy pilling and the low shortcoming of strength, after increasing polyester fiber, the contraction after absorbing can be improved
Property so that the more fluffy softness of above-mentioned spunlace non-woven cloth.Furthermore it is preferred that the second nonwoven layer 3 is spun-bonded non-woven fabrics, here
The components of spun-bonded non-woven fabrics include polypropylene fibre, spun-bonded non-woven fabrics have toughness strong, and tensile strength is high, are unlikely to deform etc. excellent
Point.
Preferably, the first nonwoven layer 1 is made of the polyester fiber into the first predetermined ratio and viscose fiber, the 3rd nonwoven
Layer of cloth 4 is made of the polyester fiber into the second predetermined ratio and viscose fiber.
First predetermined ratio and the second predetermined ratio can be adjusted according to actual conditions, according to the material market price
Change and carry out corresponding proportioning adjustment, so as to improve product cost stability.Preferably, the first predetermined ratio and the second predetermined ratio
Example is identical.
Preferably, the first nonwoven layer 1 and the 3rd nonwoven layer 4 are made by water jet process, and pulp layer 2 is by wet papermaking
Technique is made, and the second nonwoven layer 3 is made of spunbond process.
The compound nonwoven cloth that the utility model embodiment provides is answered as a result of three kinds of nonwoven layers and pulp layer
Close, not only there is original flexible, light, the easy decomposition of non-woven fabrics, but also compared to single-layer nonwoven transverse and longitudinal tension intensity
It is stronger.Further, since the addition of pulp layer, compared with common non-woven fabric, water imbibition is more preferable.Further, since compound nonwoven cloth
The thick and solid degree increase of four-layer structure, so as to make Jacquard design to the compound nonwoven cloth, and overall jacquard weave three-dimensional sense is stronger.
Above-mentioned all optional technical solutions, can use any combination to form the alternative embodiment of the utility model, herein
No longer repeat one by one.
The compound nonwoven cloth provided with reference to embodiment the utility model embodiment is described further.
Embodiment 1
Hydrophily spun-bonded non-woven fabrics layer is produced by spunbond process, is starched by wet papermaking process paper pulp with fiber suspension
Form pulp layer is produced by wet-laying in lapper, then above-mentioned double-layer structure up and down respectively increase by one layer comb
Fibre web is managed, it is for composite by water jet process, it is final to obtain the compound nonwoven cloth with four-layer structure.
In order to verify the functional effect of compound nonwoven cloth, 3 groups of 55g, tetra- layers of compound nonwoven cloths and 3 groups of 55g are taken commonly to put down respectively
Line non-woven fabrics, then measures their multiple performance indicators, and is contrasted, and obtained result is as shown in table 1 below to table 3：
Tetra- layers of compound nonwoven cloth result of the test data of table 1-55g
The common plain weave non-woven fabrics result of the test data of table 2-55g
The comparison of test results data of the four layers of compound nonwoven cloth of table -3 and common plain weave non-woven fabrics
Wherein, in above-mentioned experiment, thickness measure uses thickness measurement equipment；Transverse and longitudinal pulling force is surveyed using imported electronic fabric strength tester
Amount；Water imbibition is tested：Cut 150mm*150mm nonwoven clothes, check weighing during dry cloth, check weighing after the suspension in 1 minute 2 minutes of soaking.
From above result of the test data, under identical grammes per square metre, compared with common plain weave non-woven fabrics, four layers of composite non woven
Cloth is more fluffy, and thickness increase, water imbibition increase, transverse and longitudinal tension intensity is all preferable, and there is no vertically and horizontally difference, compared to general
Both logical plain weave non-woven fabrics are more balanced.Because common plain weave non-woven fabrics is by combing networking and then passing through water jet process system again
Into, therefore it is strong along the longitudinal direction pulling force of fiber, and lateral pull is weak；And four layers of compound nonwoven cloth are due to adding one layer of spinning
Bonded non-woven fabrics so that transverse and longitudinal tension intensity becomes balanced, and there is no vertically and horizontally difference.
The compound nonwoven cloth that the utility model embodiment provides is fluffy, soft, has preferable thick and solid degree, since thickness increases
Add, Jacquard design can be made on the compound nonwoven cloth, overall jacquard weave three-dimensional sense is stronger；Compared with common non-woven fabric, this is multiple
The water imbibition increase of non-woven fabrics is closed, there is preferable water imbibition；With higher tensile strength, transverse and longitudinal tension intensity all compared with
It is good, and there is no vertically and horizontally difference, it is more balanced compared to both common non-woven fabrics.In addition, by varying the compound nonwoven cloth
The material proportioning and each layer of material proportioning of different layers, on the one hand can change the overall performance of compound nonwoven cloth, so that
Diversified compound nonwoven cloth is provided, on the other hand can also balance material price change, improves product cost stability.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality
Within new spirit and principle, any modification, equivalent replacement, improvement and so on, should be included in the guarantor of the utility model
Within the scope of shield.
